If I configure a Connector to exclude all the fields of a table but the interested one (using --exclude-column option) I still receive Kafka events every time the record is modified regardless of the fields changed.

It would be useful to be able to configure the “skip-messages-without-change” [property](https://debezium.io/documentation/reference/stable/connectors/postgresql.html#postgresql-property-skip-messages-without-change)
